摘　　要：大长径比飞行器在高速飞行过程中会产生弹性振动,传统控制器无法进行可靠的姿态控制,引入弹性干扰下的系统模型对控制系统所需的未知参数进行在线辨识。结果验证出基于无迹卡尔曼滤波(UKF)的滤波参数辨识具有很好的准确性,为飞行器实现稳定的姿态控制奠定了基础。The large long diameter ratio aircraft generates elastic vibration during the high speed flight.The conventional controller cannot perform reliable attitude control,so the system model under elastic interference is introduced to identify the unknown parameters required by the control system online.The results verify that the filtering parameter identification based on unscented Kalman filtering(UKF)has good accuracy,which lays a foundation for the aircraft to achieve stable attitude control.
